Honeywell 8C-TPOXA1 51307153-175 Experion Series 8 PROFIBUS Gateway IOTA, Coated

Description

The Honeywell 8C-TPOXA1 (Part Number 51307153-175) is a conformal coated Input/Output Termination Assembly (IOTA) designed specifically for the Honeywell Experion LX Series 8 Distributed Control System (DCS) platform. It serves as the physical mounting and wiring interface for the Honeywell 8C-IP0102 PROFIBUS Gateway Module (PGM), enabling fieldbus communication links between field instrumentation and the controller system.

This IOTA functions as the vital connection point for external field communication cables, power distribution, and system-level interface routing. Built with factory conformal coating, the 8C-TPOXA1 is engineered to withstand harsh industrial processing environments, preventing board-level contamination and corrosion.

Features

• Dedicated Gateway Interface: Designed specifically to host the 8C-IP0102 PROFIBUS Gateway Module within the Experion Series 8 architecture.
• Conformal Coating Protection: Coated circuit board construction provides enhanced resilience against industrial airborne pollutants and moisture.
• Integrated Connectivity: Features dual FTE-A and FTE-B Ethernet link RJ-45 ports along with PBLink network interface terminals.
• Addressing Capability: Incorporates three rotary FTE Device Index switches directly on the assembly for hardware node identification.
• System Bus Isolation: Features grounded mounting interface hardware connecting to the system COM bus bar for proper ground integrity.

Applications

• Process Control Fieldbus Integration: Hosts PROFIBUS gateway modules connecting smart instrumentation to Experion Series 8 DCS controllers.
• Corrosive Processing Environments: Ideal for installation in chemical, oil and gas, or manufacturing facilities requiring conformal coated control hardware.
• Industrial Network Subsystems: Interfacing field devices with high-availability control network topologies.

Installation Guidelines

1. Verify that the system power supply is isolated or the system is off-process before mounting.
2. Confirm the IOTA hardware part number and ensure the conformal coating matches installation requirements.
3. Mount the IOTA onto the cabinet channel rail using the dedicated screws, washers, and spacers.
4. Tighten the grounding screw on the right side of the IOTA to secure connection to the cabinet COM bus bar.
5. Ensure the four main mounting screws are tightened uniformly without causing board distortion.
6. Connect the yellow Cat5 cable to the FTE-A connector and green Cat5 cable to the FTE-B connector.
7. Terminate PBLink fieldbus cables to their designated connector points.

Configuration and Replacement Recommendations

• Address Verification: Set the three rotary FTE Device Index switches to match the exact node address of the original unit prior to powering up.
• Module Seating: When installing the 8C-IP0102 gateway module onto the IOTA, ensure board edge connectors mate cleanly before tightening retention screws.
• System Load: After hardware replacement, perform a "Load with Contents" operation from Control Builder to update operational parameters.
